Thank you, I went back to the examples and after a few tests I realized I was not properly using the functions the calculate and use the pi_values. Miguel

Just to clarify, I am asking about a simple OL with latent classes because I am still intrigued by the sentence in the Apollo manual, page 75, " the Tau parameters can vary across classes". I interpret this as the Taus being a function of one class at the time, and the modeler can choose t...

Thank you for the tip Stephane, I looked at example 21 and later changed the parameters and a few things and it works now when combining a MNL model and an OL model using latent classes. It also works with just a simple MNL model and latent classes. Though, I cannot make it work with just a simple O...

hello David, Stephane, I tried a simple OL with V function related to class "b" parameters only and then I get this error message: "Error in apollo_lc(lc_settings, apollo_inputs, functionality): Arguments 'inClassProb' and 'classProb' for model component "Latent class" must ...

I think the code I pasted does not make any sense, I have tried so many combinations trying to figure out how to do it that I have lost track of what I am doing. I am lost regarding how to input the vector Tau and the V for an OL model when using two classes in the "while" loop and also wh...

Hi David, Stephane, Long-term goal, I would like to estimate a HLCM mode and this paper was my inspiration: Hoyos, David, Petr Mariel, and Stephane Hess. "Incorporating environmental attitudes in discrete choice models: An exploration of the utility of the awareness of consequences scale."...

Just to clarify, I used the simplest possible function (1 in V) for OL to troubleshoot the problem with Tau. Also, I will link the utilities later so that the models are jointly estimated but for now just trying to solve the problem with Tau and trying to keep it as simple as possible in a combined ...

Thanks, code pasted below. --- title: "Basic LC - MNL + OL " author: "MAF" date: "11/12/2020" output: html_document --- ```{r setup, include=FALSE} knitr::opts_chunk$set(echo = TRUE) ### Load Apollo library library(apollo) options(digits = 3) ``` #### LOAD LIBRARY AND D...

Thank you for Apollo and its nice features ! I have been looking at latent class models. Following examples 18 and 20 I was able to successfully implement a MNL with latent classes. Now I am trying to implement an OL model with latent classes. According to the Apollo manual Tau parameters can vary a...
